[0002] Flat keel is a new type of building material. With the development of my country's modernization construction, flat keel is widely used in hotels, terminal buildings, bus stations, stations, amusement parks, shopping malls, factories, office buildings, old building renovation, interior decoration, ceilings and other places. Flat keel has the advantages of light weight, high strength, waterproof, shockproof, dustproof, sound insulation, sound absorption, constant temperature, etc. It also has the advantages of short construction period and simple construction.

[0003] The flat keel is formed by cold bending through forming equipment. In the prior art, on the one hand, when the coil is unwound and enters the stamping equipment, it will be offset during the conveying process, resulting in asymmetric keel forming.

DETAILED DESCRIPTION

[0025] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] like Figure 1 to Figure 6 As shown, this embodiment proposes a flat keel cold bending forming integrated machine, including a frame 1 and a reeling device, a guiding device, a driving device, a transition forming device and a shaping device arranged on the frame 1 in sequence, the guiding device includes a guiding body 2 with a cavity and an adjusting roller 3 rotatably arranged in the cavity, the guiding body 2 has a feed port and a discharge port, there are a plurality of adjusting rollers 3, the axial direction of the adjusting roller 3 is the same as the guiding direction of the guiding device, the adjusting roller 3 is two layers arranged up and down, and there is a gap between the two layers of the adjusting rollers 3 for the coil to pass through.

[0027] In the present embodiment, a flat keel cold bending forming integrated machine is provided. The coil is unrolled by an unwinding device on a frame 1. The coil passes through a guide device and then is pulled to move by a driving device. The two sides of the coil are formed into inclined edges that can be folded up by a transition forming device arranged along the conveying route so as to perform transition forming for subsequent forming. Finally, the transitionally formed coil is formed in a shaping device to form a formed flat keel. In order to solve the technical problem that the offset during the conveying process causes the final formed flat keel to have a size deviation, the guide device allows the coil to pass through from the inside. An adjustment roller 3 is arranged in a cavity inside a guide body 2. The adjustment roller 3 is rotatably arranged in the cavity and its axial direction is the same as the conveying direction of the coil. When the coil enters the feed port in the guide body 2 and is output at the discharge port, if there is a position offset, the adjustment roller 3 rotates, and the roller surface rubs against the surface of the coil. Preferably, there are two layers of adjustment rollers 3, so that the contact is better. The left and right positions of the coil can be adjusted, thereby adjusting the offset of the coil, and the size of the two sides of the flat keel after the final forming is more accurate.

[0028] The adjustment roller 3 includes a main roller 4 and a friction roller 5 arranged on the main roller 4. A plurality of linear grooves 6 are arranged in sequence along the axial direction on the adjustment roller 3. The friction roller 5 is rotatably arranged in the linear groove 6. A plurality of friction rollers 5 are arranged in the linear groove 6 along the axial direction of the adjustment roller 3, and the axial direction of the friction roller 5 is perpendicular to the axial direction of the adjustment roller 3.

[0029] In this embodiment, the adjustment roller 3 is specifically a combination of a main roller 4 and a friction roller 5. An axially straight groove 6 is opened on the adjustment roller 3, and a plurality of straight grooves 6 are circumferentially arranged on the main roller 4. A plurality of friction rollers 5 are arranged in the linear groove 6 along the direction of the groove. The axial direction of the friction roller 5 is perpendicular to the axial direction of the main roller 4. When the coil contacts the adjustment roller 3, it contacts the friction roller 5. During the conveying of the coil, the friction roller 5 will rotate, reducing friction loss. When the offset needs to be adjusted, the rotation of the main roller 4 drives the friction roller 5 to rotate along the axial direction of the main roller 4, thereby adjusting the left and right offset of the coil.

[0030] The driving device comprises a driving roller 7 arranged on the frame 1, two driving rollers 7 form a group and the gap between the two driving rollers 7 is used for the coil to pass through.

[0031] In this embodiment, the driving rollers 7 are arranged in an upper and lower position structure. The coil passes through the gap between the two driving rollers 7. The driving rollers 7 rotate and drive the coil to move in the conveying direction through friction. The two driving rollers 7 arranged upper and lower are a group. In the conveying direction, multiple groups of driving rollers 7 can be selectively set according to different conveying speeds and forces.

[0032] The driving device also includes a driving bracket 8 and a clamping mechanism. The driving bracket 8 is arranged on the frame 1. The two driving rollers 7 are arranged in two layers, one above the other. The driving roller 7 of the lower layer is rotatably arranged on the driving bracket 8. The clamping mechanism includes a clamping block 9, a positioning rod 10 and a clamping spring 11. The driving roller 7 of the upper layer is rotatably arranged on the clamping block 9. The clamping block 9 is slidably arranged on the driving bracket 8 in a vertical direction. The positioning rod 10 passes through the clamping block 9. The clamping spring 11 is sleeved on the positioning rod 10. One end of the clamping spring 11 acts on the driving bracket 8, and the other end acts on the clamping block 9.

[0033] In this embodiment, the driving device is a driving bracket 8 installed on the frame 1, and the driving roller 7 is rotatably set on the driving bracket 8, wherein the lower driving roller 7 is rotatably set on the driving bracket 8, and the upper driving roller 7 is rotatably connected to the clamping block 9, and the clamping block 9 is vertically slidably connected to the positioning rod 10, and the positioning rod 10 is vertically installed on the driving bracket 8. By arranging a clamping spring 11 on the positioning rod 10, the elastic force of the clamping spring 11 is used to press the clamping block 9, so that the upper driving roller 7 is pressed on the lower driving roller 7 to ensure that there is sufficient friction force to drive the coil to move.

[0034] The transition forming device comprises an inclined transition roller group, a right-angle transition roller group and a vertical edge shaping roller group which are sequentially arranged on the frame 1 along the direction of coil conveying.

[0035] In this embodiment, in the direction of coil conveying, the edges of both ends of the coil are gradually tilted and shaped by installing inclined transition roller groups in sequence to achieve a gradually inward-retracted state, and then the inclined parts at both ends of the coil are formed at right angles through the roller group through the right-angle transition roller group, and finally the formed right-angled edges are finally shaped through the vertical edge shaping roller group.

[0036] The inclined transition roller group includes a middle conveying roller 12 and an inclined roller 13. The middle conveying roller 12 includes a group of round rollers arranged up and down. The inclined rollers 13 are arranged on both sides of the middle conveying roller 12. There are several inclined rollers 13, and the angle between the inclined rollers 13 and the middle conveying roller 12 decreases successively along the conveying direction.

[0037] In this embodiment, the middle conveying roller 12 supports the coil, and the inclined rollers 13 on both sides gradually decrease their inclination angles along the direction of coil conveying, gradually changing from an obtuse angle to a right angle. The middle conveying roller 12 is a round roller arranged up and down, which can ensure the flatness of the bottom surface.

[0038] The right-angle transition roller group includes a right-angle vertical roller 14, a bottom roller 15 and a right-angle top roller 16 arranged on the frame 1, the right-angle vertical roller 14 is arranged on both sides of the bottom roller 15, and the roller edge of the right-angle fixed roller is arranged along the inner direction of the right-angle intersection position of the right-angle vertical roller 14 and the bottom roller 15.

[0039] In this embodiment, the inclined transition roller group can achieve the effect of slow forming of the coil, and the material distribution during the coil forming process will be more balanced. When entering the right-angle transition roller group, the material at the right-angle bend will not deform rapidly like during stamping, resulting in uneven material thickness. The bottom roller 15 of the right-angle transition roller group supports the bottom surface of the middle part of the coil, and the right-angle fixed roller and the right-angle vertical roller 14 cooperate to further form the right-angle part.

[0040] The vertical edge shaping roller group includes an outer roller 17 and an inner roller 18 vertically arranged on the frame 1. The outer roller 17 and the inner roller 18 form a group and are located on both sides of the coil.

[0041] In this embodiment, the vertical edge shaping roller group clamps the coiled material that has formed the right-angle vertical edge through the outer roller 17 and the inner roller 18 to further shape the vertical edge.

[0042] The shaping device comprises a lower die 19 and an upper die 20 arranged on the frame 1 , wherein the upper die 20 is arranged on the upper portion of the lower die 19 , and a shaping space is defined between the upper die 20 and the lower die 19 .

[0043] In this embodiment, the shaping device performs final pressing and shaping on the coiled material that has initially formed the keel groove through the upper die 20 and the lower die 19. Since a right angle has been formed, the shaping will not affect the material thickness distribution at the final keel bend.

[0044] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
